Inbreeding is a central topic in evolutionary biology and ecology and is of major concern for the conservation of endangered species. Yet, it remains challenging to comprehend the fitness consequences of inbreeding, because studies typically focus only on short-term effects on inbreeding in the offspring (e.g. survival until independence).

Unification of inbreeding and parental investment theory. We consider a focal diploid parent (hereafter assumed to be a stereotypical female) that can adjust the degree to which she invests in each offspring to maximize her own inclusive fitness, defined as the rate at which she increases the number of identical-by-descent allele copies inherited by her viable offspring (γ).Inbreeding depression is thought to result biologically from (a) deleterious recessive alleles driven to homozygosity, (b) ... In United States maize production, OPVs were abandoned in the early 1920s due to the difficulty of improving their quantitative traits (i.e., ...Inbreeding commonly leads to inbreeding depression, the reduced fitness of individuals due to deleterious recessive (or partially recessive) mutations exposed in the homozygous state [8,9]. In livestock, for every 1% increase in (pedigree-estimated) inbreeding, there is an estimated 0.13% decrease in the mean selected trait value [ 10 ].Top 10 Busiest Costco Stores in Canada (2024) January 12, 2024 by shamim.

Level of Inbreeding. Based on the pedigree (details of which are given in SI Materials and Methods and Table S1), close inbreeding resulting in F ped = 0.25 is rare (n = 10 instances), and occurred only via father−daughter matings (in line with refs. 22 and 24).To minimize bias, F ped-based analysis was restricted to individuals for whom it was, at minimum, clear whether or not they were the ...

Albinism is a congenital condition characterized in humans by the partial or complete absence of pigment in the skin, hair and eyes. Albinism is associated with a number of vision defects, such as photophobia, nystagmus, and amblyopia. Lack of skin pigmentation makes for more susceptibility to sunburn and skin cancers.
